Solution Overview

Problem

Traditional barge gauging methods are hazardous, time-consuming, and inaccurate, requiring manual measurements that are often taken in dangerous conditions, and do not allow for real-time monitoring of draft and weight changes during loading and unloading.

Innovation Solution

A draft survey apparatus using LiDAR technology with a light source and receiver to emit and detect photons, determining the position of objects and surfaces in 3D space, allowing for real-time calculation of barge draft and weight based on the position of objects and surfaces relative to the light source and receiver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual measurement techniques are used to determine barge draft, then personnel can obtain draft measurements, but personnel are exposed to dangerous conditions including falling from the barge, hypothermia from icy waters, and being pinned between the barge and dock

Engineering Contradiction:
Improvedraft measurement accuracyVSAvoidpersonnel safety hazards
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical measurement systems with an automated optical measurement system. The apparatus uses a camera to capture images of the barge and waterline, and a processor automatically calculates draft measurements from these images, eliminating the need for personnel to physically measure the barge in dangerous conditions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary measurement system consisting of a camera and image processing apparatus. Instead of personnel directly measuring the barge, the camera captures visual data of the barge and waterline, and the processor serves as an intermediary to calculate the draft from these images, protecting personnel from exposure to harmful conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If personnel manually measure draft from multiple positions on the barge, then accurate draft values can be obtained, but the process is time-consuming and reduces loading/unloading efficiency

Engineering Contradiction:
Improvedraft measurement accuracyVSAvoidloading and unloading efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent enables continuous draft monitoring by capturing multiple images of the barge at different positions and continuously processing these images to calculate draft measurements. This continuous measurement capability allows for real-time monitoring of draft changes during loading and unloading operations, improving efficiency while maintaining accuracy.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent transitions from static manual measurements to dynamic automated measurements. The system can capture images and calculate draft measurements dynamically as the barge moves or changes position, allowing measurements to be taken without interrupting loading/unloading operations and improving overall productivity.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If multiple personnel are deployed to take measurements from multiple positions on the barge, then accurate draft and weight distribution data can be collected, but the complexity and time required for the gauging process increases

Engineering Contradiction:
Improveweight distribution measurement accuracyVSAvoidgauging system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a universal measurement system that can determine multiple parameters (draft, weight, weight distribution) from a single set of images using one camera and processor. This multi-functional apparatus eliminates the need for multiple personnel and separate measurement devices, reducing system complexity while maintaining measurement precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple measurement functions into a single integrated system. The camera captures images that contain information about draft and weight distribution, and the processor combines this information to calculate all required measurements, merging what would traditionally require multiple separate measurement operations into one unified process.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A draft survey apparatus for gauging a barge by determining a weight of bulk materials loaded and discharged from the barge in water wherein the water level is provided. The draft survey apparatus includes a light source for emitting photons radially outward from the light source, a receiver for receiving the photons reflected off of the barge and surface, the receiver operable to sense a return angle of the photons, and a processor operable to determine a position of the objects and surfaces in three dimensional space based on the return angle of the photons and a time delay of photons between emission and receipt. The processor is operable to determine the weight of the bulk materials on the barge based on a height of barge above the water level.
